Question

A scientist claims that only 63% of geese in his area fly south for the winter. He tags60 random geese in the summer and finds that 19 of them do not fly south in the winter.If α = 0.05, is the scientist's belief warranted?

A)Ye s, because the test value 0.86 is in the noncritical region.B)Ye s, because the test value -0.95 is in the noncritical region.C)No, because the test value 0.95 is in the critical region.D)No, because the test value -0.86 is in the noncritical region.

Answer 1

A scientist claims that only 63% of geese in his area fly south for the winter. He tags 60 random geese in the summer and finds that 19 of them do not fly south in the winter.

P= % of geese in his area fly south for the winter

we want to test the claim that only 63% of geese in his area fly south for the winter.

Ho:- P= 0.63 vs Ho: P ≠ 0.63

is the scientist's belief warranted?

A)Ye s, because the test value 0.86 is in the noncritical region
